A1280A-PQ160C

Field Programmable Gate Array Overview

The A1280A-PQ160C is a Field Programmable Gate Array (FPGA) belonging to the ACT 2 family, manufactured by Microsemi Corporation. It features 1232 Configurable Logic Blocks (CLBs) and an equivalent gate count of 8000 gates. The device supports a maximum clock frequency of 75 MHz and operates on a single 5 V supply voltage. It is housed in a 160-pin Plastic Quad Flat Package (PQFP). The component is designed for commercial temperature ranges, typically operating between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• High-density logic architecture with 1232 CLBs for complex digital system integration
• ACT 2 technology providing non-volatile configuration retention without external memory
• Single 5V power supply operation simplifying board design and power management

Field Programmable Gate Array Applications

• Complex digital signal processing implementations
• Custom interface bridging between legacy and modern systems
• Prototyping of ASIC designs requiring high logic density

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade and plastic package variant. Confirm RoHS compliance status as older ACT 2 devices may not meet current environmental standards. Check for End-of-Life (EOL) notifications or Last-Time-Buy notices from Microchip, as this part number belongs to a discontinued product line. Ensure sourcing channels provide genuine components with traceability documentation.

Field Programmable Gate Array Selection Notes

Select the A1280A-PQ160C when a high gate count FPGA is required within a 160-pin footprint constraint. Compare against the A1440A series if higher performance or different I/O counts are needed. Consider the A1280A-1CQ172GC if ceramic packaging or industrial temperature ratings are necessary instead of the plastic commercial version. Evaluate pin availability against the specific application's I/O requirements before finalizing the choice.

Field Programmable Gate Array Part Context

This component is part of the Microsemi ACT 2 FPGA family, which utilizes antifuse technology for permanent configuration. The ACT 2 series was designed to offer high performance and density compared to earlier generations. The A1280A variant represents a mid-to-high density option within this specific family, balancing logic resources with package size limitations typical of the PQFP form factor during its production era.
